Mr Pest Control

Question:

The local entomologist ID'd a sample as the carpet or hide beetle that has infested the fireplace area of our client's home. Inspecting both under and in/over the fireplace we are unable to locate a nesting area that would support this pest. The 4' crawl space was inspected twice. A chimney sweep took care of the upper works. I would like to hear any eradication ideas and recommended pesticides and application methods.

Answer:

I guess we can assume that the ID was accurate, although there can be a big difference between typical "carpet" beetles and hide beetles, with respect to the things they eat. Both kinds are in the family Dermestidae, but hide beetles are more often associated with carcasses and the final bits of skin, flesh, and hair left on the carcass once the flies and other initial insects are through with it. Typical carpet beetles feed on the hair or feathers of carcasses as well as on any grain-based food materials, so old rodent baits, bags of baking goods, dry pet foods are all susceptible to infestation from these smaller, oval beetles. Carpet beetles also feed on dead insects and their assorted remains, so old bee hives or wasp nests often have carpet beetles in them feeding on leftover pupa and shed exoskeletons. ... Read more
